Specification of Letters Patent.

I Application filed. January 19, '1909. Serial No. 478,168.

To all whom it may concern:

Be it known that I, CLARENCE G. CRISPIN, residing at 'Berwick, Columbiacounty, Penn sylvania, and being a citizen of the United States, haveinvented certainnew and useful Improvements in Fluid-Valves, of whichthe following is a full, clear, and exact descri tion, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, whichillustrate the preferred form of the invention, though it is to beunderstood that the invention is not limited to the exact details ofconstruction shown and described, as it is obvious that variousmodifications thereof will occur to persons skilled in the art.

In said drawings: Figure 1 is an elevational view partly in verticalsection. Fig. 2 is a plan view with the cover and its appurtenancesremoved. Fig. 3 is an elevational View of the inner receptacle or cupand its hanger members. Fig. 4 is an inverted plan view of the innerreceptacle. Fig. 5 is an elevational view partly in section, the sectionbeing taken on line 55 of Fig. 6, said Fig. 5 illustrating a modifiedform of construction. Fig. 6 is a ilan "iew illustrating themodification of t 1e device shown in Fig. 5 with the cover removed,showing how the device may be applied in clusters where a maximumquantity of air is to be exhausted, as from a large pipe. Fig. 7 is aninverted plan view of the inner cover used with the construction shownin Figs. 5 and 6.

My invention relates to improvements in that class of valves especiallyapplicable to or serviceable in connection with water mains o )i ms.

t has for its object to provide for venting such water mains or pipes orthe release of confined air when admitting water thereto; also, for theadmission of air thereinto when the water is withdrawn or otherwiseescapes therefrom, and to carry out these ends in a simple and effectivemanner.

Said invention therefore consists of certain structural features,substantially as hereinafter more fully disclosed, and particularlypointed out by the claims. I

In the drawings, 1 indicates the outer shell of my improved valve, whichhas ingress and egress ports with which communicate respectively thepipes 2 and 3. The shell 1 is provided. with a cover 4, which is securedin position by a suitable number of volume of fluids.

bolts 5 passing through flanges 6 and 7 of the cover and shell andbetween the cover and shell is provided a suitable packing 8 to form awatertight joint. side of the cover 4 isv a circular opening 9 and abovethis opening, that is between it and the ipe 3, is a packing 10 whichserves the dou )le function of a packing for the joint between the pi e3 and cover 4 and as a valve seat for t e ball valve hereinafterreferred to.

Suspended by the flanged straps 11 in the shell 1 is a cup or innervessel 12 which is provided with decentralized perforations 13 and inthecup 12 is a globe valve 15, which is of such diameter that when seatedin its valve seat or against the packing 10 it will close the egressport through the cover 4, and when-seated on the bottom 16 of the cup 12will leave a clear space between said globe valve and the decentralizedperforations 13 in the bottom of said cup, thereby roviding for theescape by gravlty of any iquids which may remain in the cup when thevalve 15 is in its lowermost position. It is to be noted that the cup 12is imperforate except for said decentralized perforations 13 and thestraps 11, which support the cup, are provided with flanges 17 whichrest in seats 18 provided therefor in the upper edge of the shell 1,while the packing 8 extends over the flanges 17, thereby preventing theesca e of fluids from the shell 1 except through t e pipes 2 and 3. Inaddition to the flanges 17 the straps 11 are provided with lower flanges19, which assist in centering the cup 12 in the shell 1.

In Figs. 5, 6 and 7 is illustrated a modification of the structure shownin the other figures, in which modification the four cups 12 with fourvalves 15 are rovided to permit the escape from the she 1 1 of a greaterIn this modification there is provided a cover 4 similar to the cover 4of Fig. 1 but between the cover thus rovided and the shell 1 there isprovide an intermediate cover 1 which intermediate cover is formed onits under face with four enlarged and tapered openings 9 each of whichis provided with a packing ring 10 to form valve seats vertically abovethe globe valves 15 in Fig. 5, there being a considerable space Abetween the cover 1 and the outer cover 4 of the device shown in Fig. 5to serve as an air space for the passage of air from the interior of thevalve Patented June 15, 1909.

Formed in the under shell 1 to a central orifice in the cover of ingressthe device shown in Fig. 5. In this modification the cups 12 aresupported in series by relatively U shaped straps 20, which rest uponinwardly converging supporting-arms 21, which are formed integralwith'the shell 1. The lower portions of the cups 12 are connected bymeans of straps 22 which, with the straps 20, bind the cups shown inFig. 5 firmly together so that they may be re moved as a unit,

Owing to the space A between the u per edge of the cups 12 and the valveseats t ere is clear space for the escape of air or other gases whichmay be in the water pipes, but as soon as water reaches the cups itflows through the perforations 13, over the upper ed e of thecups, andlifts the buoyant glo e valves to osition in contact with the valveseats 10, t ereby preventing escape of liquid while permitting freeescape of other fluids prior to the lifting of said valve. When thewater pressure is reduced the valves 15 drop by gravity and owing to thedecentralization of the erforations 13 the li uid in cups 12 willrainoff. Another advantage in having the perforations 13 out of contactwith the valve 15 is that the cup may be washed out to dispose ofsediment which may accumulate in the cups without removing the valve 15,which can otherwise only be done by first removing the cover 4. Thevalve being underground and communicating with the atmosphere through apipe extending up through the soil, it is evident that a greatconvenience results from such disposition of the perforations 13 in thecups, as the operation of the valves may be tested without removing thevalves from their connection with the water main. If desired, thevalves15 may seat against the metal 9, the packing 10 or both, as may bedesired.

What I claim is:

'1. In a valve of the character set forth, the combination comprising anouter shell, a cover therefor provided with a valve opening, an exhaustpipe leading from said cover, a packing between said cover and pipeforming a valve seat, a spherical valve adapted to seat against saidvalve tened bottom, said cup having decentralized perforations thereinand means for supportmg said cup in said outer shell.

2. In a gravity and liquid operated valve adapted to permit escape offluids, the combination comprising an outer shell with an seat, a cupwith flat port, a cover member with an egress port an. a valve seat, abuoyant globe valve adapted to close said egress port and a nonsphericalreceptacle for said valve, said re ceptacle being perforated in. itslower )ortion, the perforation being so positioner as to be alwavsremoved from said buoyant valve.

3. In a liquid operated valve adapted to permit escape of fluids, anouter chamber, a

perforated non-spherical cup suspended therein with decentralizedperforations in said cup, a cover for said outer chamber with a port andvalve seat and a buoyant globe- "valve relatively within said cup,adapted to cut oil communication between said chamber and said port.

4. In a liquid operated valve adapted-to permit escape of fluids, anouter chamber, a

cover therefor provided with a valve open-,

ing, a packing above said valve opening cooperating therewith to fcrm avalve seat, an exhaust pipe seated. on said packing, an'innerreceptacle, suspending means therefor resting between said. outerreoeitaole'and its cover, said inner receptacle aving decentralizedperforations therein and a globe valve adapted in one position to seatin the valve seat of the cover and in another position to rest in saidinner receptacle removed ..from the perforations therein.

5. In a cluster valve operated by liquids and adapted to permit theescape of fluids, an outer shell provided with a port and inwardlyextending supporting arms, a plurality of valve receptacles supportedfrom said arms, an inner cover provided with a pluralitv of valve seatsin alinement with said valve receptacles, and an outer cover with egressport therein.

6. In a liquid operated valve adapted to permit escape of fluids, anouter chamber, a cover therefor provided with exhaust ort and a valveseat, an exhaust pipe in aiinement with said port, an inner receptacle,suspending means for said inner receptacle and a buoyant globe valveadapted to close said exhaust port under liquid pressure, the said innerreceptacle having decentralized )erforations therein so )ositioned as tobe always removed from said globe valve.

In witness whereof I have hereunto set my hand in the presence of twowitnesses.
